SensorDelegate User Experience (Ble)

Has anyone implemented SensorDelegate for Ble that has access to a 5.1.0+ watch?

I've only got 3.4.5 on my Descent Mk2i so I'm blindly implementing by spec..

I've implemented the SensorDelegate object and included getSensorDelegate in the main app
My delegate returns pairingRequired = true always

Simulator -> Manage Sensors shows me Connect IQ / <App name> as a selection on 5.1.0+ device types

My test user is saying there doesn't appear to be any Connect IQ section in Sensors & Accessories from the system menu
He's got a Fr955 Solar running SDK 5.2.0

What should the user be seeing in the watch UI?
